It may be explicitly or implicitly understood by those skilled in the art that, embodiments described herein can be combined with other embodiments.

[0021] The electronic device described in embodiments of the present disclosure may include various devices having a wireless communication function, such as a mobile terminal, a portable device, a vehicle-mounted device, a wearable device, a computing device or other processing devices coupled to a wireless modem, and various forms of user equipment (UE), mobile stations (MS), terminal devices and the like. For ease of description, the above-mentioned devices are collectively referred to as electronic device. Embodiments of the present disclosure will be described in detail hereinafter.

[0022] In order to have a better understanding of the electronic device, the fingerprint recognition control method and device provided by embodiments of the present disclosure, embodiments of the present disclosure are described in detail hereinafter.

[0023] Referring to FIG. 1, which is a schematic diagram of an electronic device 100 according to an embodiment of the present disclosure, the electronic device 100 includes a processor 110, a touch display screen 120 and a fingerprint recognition apparatus 130. The fingerprint recognition apparatus 130 is coupled to the touch display screen 120, and a fingerprint recognition region of the fingerprint recognition apparatus 130 includes the entire touch display screen 120. The processor 110 is coupled to the touch display screen 120 and the fingerprint recognition apparatus 130 via a bus 150.

[0024] The touch display screen 120 is configured to detect a vertical distance between a touch end and the touch display screen. The touch display screen 120 is further configured to determine a vertical projection point of the touch end on the touch display screen and send the vertical projection point to the processor when it is determined that the vertical distance is less than or equal to a preset distance threshold. The processor 110 is configured to determine a target region corresponding to the vertical projection point on the touch display screen. The processor 110 is further configured to enable a fingerprint recognition function of the fingerprint recognition apparatus in the target region.

[0025] It can be seen that, in embodiments of the present disclosure, the fingerprint recognition region of the fingerprint recognition apparatus in the electronic device includes the entire touch display screen. The touch display screen of the electronic device detects the vertical distance between the touch end and the touch display screen. When it is determined that the vertical distance is less than or equal to the preset distance threshold, the touch display screen determines the vertical projection point of the touch end on the touch display screen, and sends the vertical projection point to the processor. The processor determines the target region corresponding to the vertical projection point on the touch display screen, and enables the fingerprint recognition function of the fingerprint recognition apparatus in the target region. Therefore, when the electronic device detects an approaching operation at the touch end, the fingerprint recognition function of the fingerprint recognition apparatus in the projection region corresponding to the approaching operation is enabled in advance, thus improving the speed of fingerprint recording of the electronic device. The electronic device may enable the fingerprint recognition function of the fingerprint recognition apparatus in the target region when the user's finger approaches the touch display screen. The electronic device does not need to wait for the user's finger to touch the touch display screen or press the Home button. Thus, the speed of fingerprint recording of the electronic device is enhanced. Moreover, since the electronic device does not need to enable the fingerprint recognition function of the entire touch display screen, and only needs to enable the fingerprint recognition function of the corresponding projection region according to the approaching operation of the user's finger, power consumption of the electronic device is reduced.

[0026] In some possible implementations, the processor 110 is further configured to highlight the target region.

[0027] Therefore, in an embodiment, after the fingerprint recognition function of the fingerprint recognition apparatus in the target region is enabled through the processor, the electronic device may highlight the target region, such that the user is guided to input the fingerprint, thereby improving the speed for fingerprint recording.

[0028] In some possible implementations, the processor 110 is configured to determine the target region corresponding to the vertical projection point on the touch display screen as follows. The processor 110 determines the vertical projection point of the touch end on the touch display screen when determining that a period in which the vertical distance between the touch end and the touch display screen is maintained less than or equal to the preset distance threshold is greater than or equal to a preset period. For example, the preset period may be 3 seconds. When the vertical distance between the touch end and the touch display screen is maintained less than or equal to the preset distance for more than 3 seconds, the processor 110 determines the vertical projection point of the touch end on the touch display screen.

[0029] Therefore, in an embodiment, when the vertical distance is less than or equal to the preset distance threshold, and when the period in which the vertical distance between the touch end and the touch display screen is maintained less than or equal to the preset distance threshold is greater than or equal to the preset period, the electronic device performs operations of controlling the touch display screen to determine the vertical projection point of the touch terminal on the touch display screen. Thus, it is beneficial to avoid user's misoperation and reduce the power consumption of the electronic device.

[0030] In some possible implementations, the processor 110 is configured to highlight the target region as follows. In detail, the processor 110 is configured to acquire first brightness of the touch display screen, and to set brightness of the target region as second brightness according to the first brightness. The second brightness is brighter than the first brightness, and the target region having the second brightness is configured to guide a user to input the fingerprint. Alternatively, the processor 110 is configured to display a man-machine interface in the target region, in which the man-machine interface is configured to guide the user to input the fingerprint in the target region.

[0031] In some possible implementations, the fingerprint recognition apparatus 130 is configured to collect fingerprint data and send the fingerprint data to the processor 110. The processor 110 is further configured to perform a matching between the fingerprint data collected and pre-stored fingerprint template data, and to perform a preset operation when the collected fingerprint data matches with the pre-stored fingerprint template data.

[0032] FIG. 2 is a flow chart of a fingerprint recognition control method according to an embodiment of the present disclosure. The method is applied to an electronic device including a touch display screen and a fingerprint recognition apparatus, and a fingerprint recognition region of the fingerprint recognition apparatus includes the entire touch display screen. As illustrated in FIG. 2, the fingerprint recognition control method according to embodiments of the present disclosure may include the following.

[0033] At block 201, a vertical distance between a touch end and the touch display screen is detected.

[0034] As illustrated in FIG. 3, the electronic device 100 includes the touch display screen 120 and the fingerprint recognition apparatus 130. The fingerprint recognition region of the fingerprint recognition apparatus 130 of the electronic device 100 includes the entire touch display screen 120.

[0035] In some possible embodiments, the touch display screen 120 may include a touch screen and a display screen, the touch screen and the display screen are arranged in a stack and the display screen is located underneath the touch screen. The fingerprint recognition apparatus 130 includes a fingerprint sensor, and the fingerprint sensor may include at least one of an optical fingerprint sensor, a capacitive fingerprint sensor and an ultrasonic fingerprint sensor.

[0036] In a case that the fingerprint sensor is the capacitive fingerprint sensor and the touch screen included in the touch display screen is a capacitive screen, the fingerprint recognition apparatus may be coupled to the touch display screen in following manner: the fingerprint recognition apparatus is integrated to the touch display screen. In an embodiment, a first induction capacitor array in the fingerprint recognition apparatus may be embedded in a second induction capacitor array in the touch display screen, and induction capacitors in the first induction capacitor array are distributed uniformly in the first region.

[0037] In a case that the fingerprint sensor is the optical fingerprint sensor, the fingerprint recognition apparatus may be coupled to the touch display screen in following manner: the fingerprint recognition apparatus is integrated to the touch display screen, the fingerprint recognition apparatus in the electronic device may collect users' fingerprint data based on a pinhole imaging principle. A spacer layer between the touch screen and the display screen included in the touch display screen is provided with a first pinhole array layer at a first preset region. A uniformly-distributed pinhole array is formed at a second preset region when a drive circuit layer of the display screen is printed. The pinhole array uniformly distributed on the drive circuit layer is regarded as a second pinhole array layer, and pinholes of the first pinhole array layer have a one-to-one correspondence with those of the second pinhole array layer. The optical fingerprint sensor may include a charge coupled device (CCD) array layer configured to detect light passing through the first pinhole array layer and the second pinhole array layer. The first preset region and the second preset region correspond to the first region respectively.

[0038] In a case that the fingerprint sensor is the ultrasonic fingerprint sensor, the fingerprint recognition apparatus may be coupled to the touch display screen in following manner: a vacuum detecting cavity is set below the first region of the touch display screen, a plurality of ultrasonic sensors are distributed uniformly in the vacuum detecting cavity. The ultrasonic sensor includes an ultrasonic signal transmitter and an ultrasonic signal receiver. The ultrasonic signal transmitter is configured to transmit signal at a certain frequency to detect the user's fingerprint, and the ultrasonic signal receiver is configured to receive an echo signal reflected. An operating principle of the ultrasonic sensor is explained as follows, by using a capacity of penetrating materials of ultrasonic waves, different echo signals may be generated according to different materials, for example, when the ultrasonic wave reaches surfaces of different materials, the ultrasonic wave may be absorbed and reflected to different extents, such that positions of ridge and valley of fingerprint may be detected.

[0039] The display screen may be a thin film transistor-liquid crystal display (TFT-LCD), a light emitting diode (LED) display, an organic light-emitting diode (OLED) display and the like.

[0040] At block 202, when it is determined that the vertical distance is less than or equal to a preset distance threshold, a vertical projection point of the touch end on the touch display screen is determined.

[0041] At block 203, a target region corresponding to the vertical projection point on the touch display screen is determined.

[0042] The target region may be a circular region with the vertical projection point as a center and a preset length as a radius, or the target region may be a square region with the vertical projection point as a center and a preset length as a side. The target region may also be regions of other shapes, which is not limited in embodiments of the present disclosure. The area of the target region is greater than a preset threshold. The preset threshold may be a contact area between a user's finger and the touch display screen when the user inputs the fingerprint.

[0043] At block 204, a fingerprint recognition function of the fingerprint recognition apparatus in the target region in enabled.

[0044] In a case that the fingerprint sensor is the capacitive fingerprint sensor and the touch screen included in the touch display screen is a capacitive screen, the induction capacitor array of the fingerprint recognition apparatus in the target region may be enabled by the electronic device, such that the fingerprint recognition function of the fingerprint recognition apparatus in the target region is enabled.

[0045] In a case that the fingerprint sensor is the optical fingerprint sensor, the electronic device may enable a charge coupled device (CCD) array layer of the optical fingerprint sensor in the target region, so as to detect light passing through the first pinhole array layer and the second pinhole array layer in the target region, thereby enabling the fingerprint recognition function of the fingerprint recognition apparatus in the target region.

[0046] In a case that the fingerprint sensor is the ultrasonic fingerprint sensor, the electronic device may enable an ultrasonic sensor in the vacuum detecting cavity set below the target region, thereby enabling the fingerprint recognition function of the fingerprint recognition apparatus in the target region.

[0047] Therefore, when the electronic device detects an approaching operation at the touch end, the fingerprint recognition function of the fingerprint recognition apparatus in the projection region corresponding to the approaching operation is enabled in advance, thus improving the speed of fingerprint recording of the electronic device. Moreover, since the electronic device does not need to enable the fingerprint recognition function of the entire touch display screen, and only needs to enable the fingerprint recognition function of the corresponding projection region according to the approaching operation of the user's finger, power consumption of the electronic device is reduced.

[0048] In some possible embodiments, the method further includes the following. The target region is highlighted.

[0049] Therefore, in an embodiment, after the fingerprint recognition function of the fingerprint recognition apparatus in the target region is enabled through the processor, the electronic device may highlight the target region, such that the user is guided to input the fingerprint, thereby improving the speed of the fingerprint recording.

[0050] In some possible implementations, the vertical projection point of the touch end on the touch display screen may be determined as follows. The vertical projection point of the touch end on the touch display screen is determined when it is determined that a period in which the vertical distance between the touch end and the touch display screen is maintained less than or equal to the preset distance threshold is greater than or equal to a preset period.

[0051] Therefore, in this embodiment, when it is determined that the vertical distance is less than or equal to the preset distance threshold, and when it is determined that the period in which the vertical distance between the touch end and the touch display screen is maintained less than or equal to the preset distance threshold is greater than or equal to the preset period, the electronic device performs operations of controlling the touch display screen to determine the vertical projection point of the touch terminal on the touch display screen. Thus, it is beneficial to avoid the user's misoperation and reduce the power consumption of the electronic device.

[0052] In some possible implementations, the target region is highlighted as follows. The electronic device acquires first brightness of the touch display screen and sets brightness of the target region as second brightness according to the first brightness. The second brightness is brighter than the first brightness, and the target region having the second brightness is configured to guide a user to input the fingerprint. Alternatively, the electronic device displays a man-machine interface in the target region, in which the man-machine interface is configured to guide the user to input the fingerprint in the target region.

[0053] In some possible implementations, the method further includes follows. The electronic device controls the fingerprint recognition apparatus to collect fingerprint data. The electronic device performs a matching between the fingerprint data collected and pre-stored fingerprint template data, and performs a preset operation when the collected fingerprint data matches with the pre-stored fingerprint template data.

[0054] FIG. 4 is a flow chart of a fingerprint recognition control method according to another embodiment of the present disclosure. Similarly, the fingerprint recognition control method according to another embodiment of the present disclosure may be applied to an electronic device including a touch display screen and a fingerprint recognition apparatus, and a fingerprint recognition region of the fingerprint recognition apparatus includes the entire touch display screen. As illustrated in FIG. 4, the fingerprint recognition control method according to embodiments of the present disclosure may include the following.

[0055] At block 301, a vertical distance between a touch end and the touch display screen is detected.

[0056] At block 302, when it is determined that the vertical distance is less than or equal to a preset distance threshold and when it is determined that a period in which the vertical distance between the touch end and the touch display screen is maintained less than or equal to the preset distance threshold is greater than or equal to a preset period, a vertical projection point of the touch end on the touch display screen is determined.

[0057] At block 303, a target region corresponding to the vertical projection point on the touch display screen is determined.

[0058] At block 304, a fingerprint recognition function of the fingerprint recognition apparatus in the target region is enabled.

[0059] At block 305, the target region is highlighted.

[0060] In detail, the electronic device may highlight the target region as follows. The electronic device acquires first brightness of the touch display screen, and the electronic device sets brightness of the target region as second brightness according to the first brightness. The second brightness is brighter than the first brightness, and the target region having the second brightness is configured to guide a user to input the fingerprint. Alternatively, the electronic device may display a man-machine interface in the target region, in which the man-machine interface is configured to guide the user to input the fingerprint in the target region.

[0061] At block 306, the fingerprint recognition apparatus is controlled to collect fingerprint data.

[0062] At block 307, a matching is performed between the fingerprint data collected and pre-stored fingerprint template data and a preset operation is performed when the collected fingerprint data matches with the pre-stored fingerprint template data through the processor.

[0063] Therefore, when the electronic device detects an approaching operation at the touch end, the fingerprint recognition function of the fingerprint recognition apparatus in the projection region corresponding to the approaching operation is enabled in advance, thus improving the speed of fingerprint recording of the electronic device. Moreover, since the electronic device does not need to enable the fingerprint recognition function of the entire touch display screen, and only needs to enable the fingerprint recognition function of the corresponding projection region according to the approaching operation of the user's finger, power consumption of the electronic device is reduced.

[0064] FIG. 5 is a schematic diagram of an electronic device according to an embodiment of the present disclosure. As illustrated in FIG. 5, the electronic device includes a processor, a touch display screen, a fingerprint recognition apparatus, a memory and one or more programs. A fingerprint recognition region of the fingerprint recognition apparatus includes the entire touch display screen.

[0065] In some possible implementations, the one or more programs further include instructions for performing following acts: highlighting the target region by the processor.

[0066] In some possible implementations, the instructions are further configured to perform following acts to determine the vertical projection point of the touch end on the touch display screen: controlling the touch display screen to determine the vertical projection point of the touch end on the touch display screen when it is determined that a period in which the vertical distance between the touch end and the touch display screen is maintained less than or equal to the preset distance threshold is greater than or equal to a preset period.

[0067] In some possible implementations, the instructions are further configured to perform following acts to highlight the target region by the processor: acquiring first brightness of the touch display screen by the processor; and according to the first brightness, setting brightness of the target region as second brightness by the processor. The second brightness is brighter than the first brightness, and the target region having the second brightness is configured to guide a user to input the fingerprint. Alternatively, the instructions are further configured to perform following acts to highlight the target region by the processor: displaying a man-machine interface in the target region by the processor, in which the man-machine interface is configured to guide the user to input the fingerprint in the target region.

[0068] Therefore, when the electronic device detects an approaching operation at the touch end, the fingerprint recognition function of the fingerprint recognition apparatus in the projection region corresponding to the approaching operation is enabled in advance, thus improving the speed for fingerprint recording of the electronic device. Moreover, since the electronic device does not need to enable the fingerprint recognition function of the entire touch display screen, and only needs to enable the fingerprint recognition function of the corresponding projection region according to the approaching operation of the user's finger, power consumption of the electronic device is reduced.

[0081] Therefore, when the electronic device detects an approaching operation at the touch end, the fingerprint recognition function of the fingerprint recognition apparatus in the projection region corresponding to the approaching operation is enabled in advance, thus improving the speed of fingerprint recording of the electronic device. Moreover, since the electronic device does not need to enable the fingerprint recognition function of the entire touch display screen, and only needs to enable the fingerprint recognition function of the corresponding projection region according to the approaching operation of the user's finger, power consumption of the electronic device is reduced.
